Fingernails grow faster than toenails, but the exact mechanisms that control the speed of nail growth are unknown. The average fingernail growth rate is faster than that of toenails (3.47mm/month compared to 1.62mm/month). There are two generally accepted theories as to why fingernails grow faster. The first is that the more you use a digit, the faster the nail grows, which is known as terminal trauma. The second theory is that fingernails grow faster because they are closer to the heart and receive more blood.
| Characteristics | Values |
|---|---|
| Average growth rate of toenails | 1.6 millimeters per month |
| Toenail growth rate dependent on | Age, sex, season, exercise level, diet, hereditary factors |
| Toenail growth faster than fingernails | Friction and fungus thicken toenails, calcium-rich toenails, proximity to the heart |
| Toenail growth slower than fingernails | Fingernails undergo more trauma, constant use increases nail growth rate |
| Toenail growth and health | Malnutrition and thyroid disease slow down nail growth, biotin supplements increase nail strength and growth rate |
| Toenail growth and health concerns | Toenails growing upward could be hereditary, toenail issues like Onychogryphosis and Nail Patella Syndrome may require medical attention |
| Toenail maintenance | Trim toenails regularly, maintain hygiene, avoid cutting nails when wet, keep feet clean and dry |

What You'll Learn
Toenails grow faster in younger people and slow with age
Toenails grow at an average rate of 1.62 millimetres per month, which is slower than the average growth rate of fingernails. Several factors influence the rate of nail growth, including age, sex, season, exercise level, diet, and hereditary factors. Toenails grow faster in younger people and slow with age due to a variety of reasons. Firstly, as people age, their blood circulation slows down, which can lead to slower nail growth. This is because the heart, being the source of blood circulation, is closer to the fingers than the toes, resulting in faster fingernail growth.
Hormone levels also play a role in nail growth rates, with puberty being a significant factor. Nail growth is said to peak during puberty and gradually decline as hormone levels balance out with age. Additionally, during pregnancy, hormone changes can cause rapid nail growth, while lactation may decrease nail growth rates.
Nutrition is another factor that affects nail growth. A diet lacking in vitamins and minerals can impact nail growth. For example, iron deficiency has been associated with nail changes, including ridges, changes in shape, and slowed growth. Taking supplements such as biotin, vitamin C, vitamin E, iron, zinc, and calcium can promote healthy nail growth and prevent deficiencies that may slow nail growth in older adults.
Furthermore, the shape and size of nail beds are influenced by genetics, which also play a role in nail growth rates. While genetics may determine faster nail growth in some individuals during their youth, age-related changes like grey hair and hair loss can still cause a slowdown in nail growth over time.
In summary, toenails grow faster in younger people due to various factors such as blood circulation, hormone levels, nutrition, and genetics. However, as individuals age, their bodies undergo changes that lead to a general slowdown in nail growth, resulting in slower-growing toenails over time.

Fingernails grow faster than toenails
Another theory posits that nail growth rate is directly related to the amount of blood flowing through the digit. Since the hands are located closer to the heart than the feet, there is a higher blood flow to the fingers, contributing to faster fingernail growth. This theory also considers the impact of temperature on blood flow, as nails tend to grow slower in cold weather when blood circulation slows down.
It's worth noting that nail growth rates can vary depending on various factors, including age, sex, season, exercise level, diet, and hereditary factors. For example, nails grow faster during the summertime and on the dominant hand, which is typically used more often. Additionally, nail growth rates can be influenced by hormonal changes during pregnancy and puberty.
While the exact mechanisms behind the faster growth of fingernails remain a subject of speculation, it is clear that they outpace the growth of toenails. On average, fingernails grow at a rate of about 3.47 to 3.5 millimeters per month, while toenails grow at a slower pace of approximately 1.6 to 1.62 millimeters per month.

Toenails are generally subjected to less trauma than fingernails
Toenails generally grow at a slower rate than fingernails, at about 1.6 millimetres per month compared to 3.5 millimetres for fingernails. One theory for the discrepancy in growth rates is that the more you use your fingernails, the more the body compensates by speeding up nail growth. Toenails are generally subjected to less trauma than fingernails, which may explain why they grow more slowly. While you may stub your toe from time to time, this temporary burst of circulation won't have a lasting impact on toenail growth.
Fingernails, on the other hand, are more susceptible to trauma due to frequent use. Catching your nail on a snag or hitting it with a hammer, for example, can cause trauma to the nail. In response, the body naturally sends more blood and nutrients to the area to aid in repair, which may contribute to faster nail growth. Additionally, the proximity of the fingers to the heart may also influence nail growth rates, with the hands receiving a greater supply of blood circulation.
The growth rate of toenails can be influenced by various factors, including friction from socks and shoes, weight-bearing, and nail fungus. Toenails are typically thicker than fingernails due to the higher concentration of calcium in the feet, which can make them stronger and more resistant to breakage. However, nail fungus can affect the protective outer layer of nails, causing overproduction and resulting in thick, yellowed, and hard toenails.
While toenails may be less prone to physical trauma, they can be affected by other factors such as upward growth, known as onychogryphosis. This condition is often caused by tight shoes pushing against the toenails or profuse foot sweating, leading to thick and curved nails. Maintaining good foot and toenail hygiene is crucial, especially in public places like gyms and swimming pools, to prevent infections and other issues. Regular trimming with sharp nail clippers and proper drying techniques are recommended to keep toenails healthy.
In summary, the difference in growth rates between toenails and fingernails can be attributed to a combination of factors, including trauma, circulation, and the unique characteristics of toenails. While toenails generally experience less trauma, they may be influenced by other factors that contribute to their growth and overall health.

Calcium in the body settles in the feet, aiding toenail growth
Calcium is an essential mineral for keeping the body strong and functional. While calcium is mostly stored in the bones and teeth, nails also contain calcium, albeit at a much lower concentration.
Calcium-deprived nails tend to grow very slowly. This is because a calcium deficiency can weaken your bones and nails. Calcium-rich diets or supplements can help combat this.
The rate at which nails grow varies from person to person. Typically, fingernails grow faster than toenails. However, friction and fungus can thicken toenails, causing them to grow faster. Calcium is heavy, so most of it settles in the feet, making it easier for toenails to access the nutrients they need to grow faster.
Toenails are also made from dead skin tissue, which is two to three times thicker on the toes than on the fingers. This thickness could also contribute to the perception that toenails grow faster.

Toenails grow faster in the summer
Toenails typically grow at a slower rate than fingernails, at about 1.6 millimetres per month. However, there are several factors that influence nail growth, including age, sex, season, exercise level, diet, and hereditary factors.
Nail growth is said to peak during puberty and then decline as hormone levels balance out with age. The nails on the dominant hand, for instance, are said to grow faster because they are used more often. This increases the risk of trauma, which causes the body to send more blood and nutrients to the affected area, potentially speeding up nail growth.
Similarly, toenails may grow faster in the summer due to increased trauma and friction from wearing open-toed shoes, sandals, or flip-flops. The extra friction from footwear can cause the nail to thicken as a protective response. Toenails are also more susceptible to nail fungus, which can affect nail growth.
Additionally, calcium plays a role in toenail growth. Since calcium is heavy, it tends to settle in the feet, making it easier for toenails to access the nutrients necessary for faster growth.
While there are no scientifically proven methods to make nails grow faster, maintaining a healthy diet with sufficient vitamins and minerals can promote overall nail health. Biotin supplements, in particular, have been found to reduce nail breakage and enhance nail health.
